LAMP-SHADE HOLDER.

Specification of Letters Patent.

.Patented July 8, 1 913.

To all 007mm i may concern:

.le it known that l, lFnANIt J. Na'irnis, a citizen olf the United States, and a resident ol Cleveland, county ot Cuyahoga, and State of Ohio, have invented a new and use'tul Improvement Yin Lamp-Shade llolders, o'l which the 'following 'is a` specification, the principle ot the invention being herein ex plained and the best mode in which l have contemplated apl'ilying that principle, so as to distinguish it Ltrom other inventions.

The present invention relates generally to lamp shade holders, and it particularly provides a holder 'tor securing a shade to the usual socketl for an incandescent electric lamp.

The invention in'ovides a lamp shade holder which may be easily and quickly secured on a socket and which may be removed with equal facility, it' desired, and which, nevertheless, will be very scciu'cly retained in place on the socket against any but in `tentional removal.

The invention provides these charzwteris- 'tics in a shade holder which is a unitary structure lending 'itself to very economical manufacture.

To the accomplishment of the toregoing and related ends, said invention, then, consists otl the means hereinafter t'ully described and particularly pointed out in the claims.

The annexed drawing and the 'following description set torth in detail certain meclr anism embodying the invention, such disclosed means constituting, however. but one ot the various mechanical 'torms in which the principle of the invention may be used.

ln said annexed drawing:Mliigure 't is a broken sectional View oft a shade holder em hodying the invention, in place on a lamp socket; Fig. 2 is a perspective view o'li a shade holder embodying the invention, and Fig. is a sectional view oli a shade holder elnbodying a modified f'orm o't' the invention.

The usual electric lamp socket 1 is provided with a cylindrical section Q formed with an outwardly projecting annular bead 3, and the socket is designed to receive an incandescent lamp 4.

The improved shade holder comprises a continuous member designed to surround the outer or lamprecei ving end of the socket in* wardly beyond the bead, and it is provided r with a flange extending outwardly 'trom the member toward the outer end ot' the socket, the flange also snrianimling the cylindrical section ol a lamp socket. lhe flange is split axially and is torined interiorly with an an n ular groove.

ln applying' the holder to a socket, the continuous membra' is passed inwardly 'from the outer or lamp receiving end oit the socketA over the bead and the flange, a portion 0lE which is designed to closely lit the outer end ot' the socket, will be sprung over the bead on the socket because ot the axial split in the flange. When the groove in the band registers with the bead, the flange will spring into its closely fitting position and tightly grip the head. 'lhe 'flange is thus securely held on the socket, and the only way it can be removed by tipping the holder or socket at a slight angle to the axis ol the socket and thus prying, so to speak, the flange 'from its gripping position on the bead of the socket. I'lhe removal o't the shade does not necessitate entirely 1 \'ing the flange ilrom the socket, but it; may be removed by a very slight angular tipping. `tollmved bj a slight rotative movement.

Despite the acilit y with which the holder may be applied to, or removed from, the socket` when once in place it is very securely held. Since the split tlange extends outwardly 'trom the continuous member, and since the. shade, which will be secured to the continuous member, extends outwardly in the same direction with the flange, the rreater the, outward pull exerted upon the continuous inemliel.' by the, shade, the more closely will the split flange be tort-ed around the socket. Obviously. il" the split flange extended inwardly` and the shade extended outwardly, lrom the lamp receiving end of the socket, the weight olt the shade, or any pull upon it, would tend to A["oree the flange troin its engaging position upon the socket. A holder embodying the present invention, however. when once applied to a socket is securely held in place against any but intentional displacen'lenty despite the lact that such intentional disl'rlacement may be easily cflectcd.

'ln the preferred t'ornl ol the invention the continuous member is vformed as an apertured anruilar web it'ornied :integrally at the edge ot the l'ierioration with an inner .flange t5, while an outer flange i projects lroni, the web in the saine direction, the

shade 8 being either permanently secured'l by rivets or otherwise, to the outer flange 7, or else the flange 7 being adapted to have a shade removably secured to it. The perforation in the web 5 is of such size as to permit the web to pass over the bead 3 on the socket. The inner flange is provided interiorly with an annular groove 9 designed to engage the bead 3 on the socket, and it is further provided with one or more axial slits 10; since the outer grooved portion -of the flange is designed to conform with the shape of the socket it will preferably be cylindrical, but from substantially the inner edge of the groove 9 to the edge of the aperture in the web 5, the flange is of general conical form so that as the holder is thrust onto the socket the split flange will be distended until the groove 9 registers with the bead 3. It will of course be noted that it is necessary, and the necessity is met by the construction just described, that the continuous web shall have an opening of such area as to permit the web to pass freely from the lamp-receiving end of the socket inwardly over the bead or vice versa; that at least that portion of the flange in which the groove is formed shall be so proportioned that the groove will closely engage the bead; and that the flange, from the grooved portion to the continuous web shall flare, or otherwise extend, until the opening therethrough is equal to or larger than the area of the aperture in the continuous web. The shade holder embodying this preferred form of the invention may be readily slipped onto the lamp receiving end of a socket, the continuous member, which will pass inwardly over the bead, holding the inner edge of the flange in fixed position, while the flange proper, because of the split or splits in it, will have sufficient resiliency to pass over the bead on the socket until the groove registers therewith, whereupon the flange will spring into securing position. The holder will, of course, be preferably made of sheet metal having some resiliency. Vhen the holder is thus in securing position, any pull outwardly upon it will serve to force the split ange more closely into gripping position against the lamp socket, so that the shade is securely held against movement in any direction. When it is intentionally desired to remove the holder, however, a slight tipping of it, due to the resiliency of the split flange, will force Ythe bead for a slight part of its length from theV groove in thel flange, and a slight rotative movement will then disengage the flange completely from the bead, and it then will be freely removable.

Fig. 3 discloses a modified form of the invention in which the continuous member l1 is formed integrally with the outer flange 12, and with an ornamental portion 13 designed to completely cover, with the flange, the cylindrical section of the usual lamp socket. The inner flange 11i provided with a groove 15 and the slit or slits 16 is made as a separate piece and secured to the mem ber 1l by rivets or by other desired means. The same general features which characterize the form already described are present in the modified form shown in Fig. 3, and the functional operation of the two forms is the same.

@ther modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed provided the means stated by any of the following claims or the equivalent of suoli stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. A shade holder designed for use with a lamp socket having a peripheral bead, comprising an apertured continuous member adapted to pass over such bead and Vdesigned to be disposed inwardly therebeyond when in position, the member being provided with an outwardly extending ange formed interiorly with a groove adapted to removably engage such bead.

2. A shade holder designed for use with a lamp socket having an annular bead, comprising adapted to pass over such bead and designed to be disposed inwardly therebeyond when in position, the member being provided with an outwardly extending flange having a substantially cylindrical portion formed interiorly with a groove adapted to removably engage such bead.

3. A shade holder designed for use with an annular continuous memberf a lamp socket having an annular' bead, comprising an annular continuous web adapted to pass over such bead and designed to be disposed inwardly therebeyond when in p0- n sition, the web being provided at its inner edge with an outwardly extending flange having a cylindrical portion formed intev 5. A shade holder designed for use with a lamp socket having an annulanbead, comprising an annular continuous web adapted to pass over such bead, the web` being pro-y edge with n second l-lnge extending in the seine direction as the inner flange.
